β-dicarbonyl compounds with their enol forms, a 1,3-dipolar cycloaddition of the enol forms with the aryl azides (high activation energy), and a dehydration process (lower activation energy). The effect of non-conventional activation methods on the degradation of 1,2,3-triazolines was next studied experimentally. Finally, some of the 1,2,3-triazoles such synthesized were evaluated for their bactericidal and
一方面是由芳基叠氮化物进行反应,另一方面是由β-二羰基化合物或丙二腈衍生的活化烯烃,通过常规加热或微波活化,得到1-芳基-1 H-1,2,3-三唑 理论上已经使用DFT方法在B3LYP / 6-31G *水平上研究了涉及β-二羰基化合物的反应机理和区域选择性:它们是包含β-二羰基化合物及其烯醇形式的互变异构平衡的多米诺过程。烯醇的1,3-偶极环加成与芳基叠氮化物(高活化能)和脱水过程(较低活化能)形成。接下来通过实验研究非常规活化方法对1,2,3-三唑啉降解的影响。最后,评估了这样合成的一些1,2,3-三唑的杀菌和细胞毒性活性。
